Although the river landscape in the Petišovci section can be considered natural, we witnessed numerous human activities (sand exploitation, logging, tourism, recreation areas, farming, pastures, military purposes, etc.). Gravel mining continues to have the greatest impact on the riverbed, impeding natural accumulations such as islands and gravel bars. It also affects the extent of humidification of inland oxbow lakes, which dry up as a result. The oxbow lakes contain a variety of plant and animal species that thrive in both summer and winter.
